Today I found on a cemetery an old paper. I was very surprised, because I could decipher the name "Eastman Kodak". Of course I picked it up. At home I restored the paper a little bit, because another layer of paper was in various quarters over the Kodak paper.
I found an interesting link, perhaps it is more or less 100 years old. I don't know, but it is a part of the history of photography.
